| abstract |
1449532 Vat and pigment dyestuffs CIBAGEIGY AG 24 Jan 1974 [30 Jan 1973] 03278/74 Heading C4P Novel dyestuffs of Formula I where R 1 and R 2 are hydrogen or C 1-4 alkyl and A 1 and A 2 are vattable radicals having 3 to 8 condensed rings may be prepared by condensing, in a molar ratio of 2 : 1, a compound of formula A 1 -Z 1 or A 2 -Z 2 or a mixture of the two with a compound of Formula II where either Z 1 and Z 2 are each halogen and Y 1 and Y 2 are -NHR 1 and -NHR 2 or Y 1 and Y 2 are each halogen and Z 1 and Z 2 are -NHR 1 and -NHR 2 . The dyestuffs of Formula I give blue to red shades when used to dye and print cellulosic fibres or in pigment applications. |
